HAULAGE MECHANISM Filed April 8. 1922 Patented Dec. 24, 19 29 UNITEDSTATES PATENT OFFICE ROBERT C. OSGOOD, OF CLAREMONT, NEW HAMPSHIRE,ASSIGNOR TO SULLIVAN MACHINERY COMPANY, A CORPORATION OF MASSACHUSETTSHAUL-AGE MECHANISM Application filed April 8,

My invention relates to haulage mechanism. An object of my invention isto provide an improved hoisting or haulage mechanism.

Another object of my invention is to provide 5 an'improved mechanism ofthe type in which the motor is enclosed within the hoist drum.

A further object of my invention is to provide an improved haulagemechanism of the type in which the driving motor is enclosed in the 1drum and the drum itself shall constitute one haulage means, whileauxiliary haulage means is also provided. Other objects and advantagesof my invention will hereinafter more fully appear.

In the accompanying drawing I have shown for purposes of illustrationone form which my invention may assume in practice.

In this drawing,

The view is a central vertical section 6 through the illustrativeembodiment of my improved mechanism.

In its illustrative form my improved mechanism is disclosed ascomprising a rotating drum 1 journaled in a U-shaped support 2.

1' The drum comprises a central portion 3 and end portions 4 and 5, thelatter being provided with stub shafts 6 and 7, of which the former is journaled in a standard or upstanding hanger 8 forming a part of theframe 2,

'30 while the latter is journaled within an annular member 9 which is inturn journaled in a standard or upstanding hanger 10 arranged at theopposite end of the frame 2. My improved haulage mechanism, as shownherein,

-35 is of the fluid pressure driven type; and enclosed within thecentral section 3 of the drum is an improved driving motor comprising apair of rotors 12 and 13 journaled in the head 4 and in an intermediatehead 14 46 which is arranged within the drum and spaced a short distancefrom the head 5. The rotors 12 and 13 are provided with intermeshingtooth blades 15 which cooperate to form pockets or chambers which expandin volume as 45 rotation of the rotors takes place, and suit- 1922.Serial No. 550,888.

chambers 18 and 19 at opposite ends of the rotors; and the expandedfluid will be freed from the interior of the drum in any suitablemanner, as by ports in the head 4, not shown. The rotor 12 is providedwith a shaft 20 extending through the intermediate head 14 and carryinga driving pinion 21 which drives a larger gear 22 fixed to a shaft 23which is journaled in the heads 14 and 5 and which carries a smallerpinion 24 meshing with and driving a larger gear 25. The latter is fixedto a rotatable shaft 26 which extends through the head 5 and at itsopposite end carries a pinion 27 which in turn meshes with a gear 28journaled on a stud or stub shaft 29 fixed to the head 5 adjacent theperiphery thereof. The gear 28 meshes with an internal gear 30 formed atthe inside of a collar 31 which is supported upon a plate 32 secured toor, as shown herein, formed integral with the sleeve 9.

Suitable braking means comprising a braking surface 33 formed upon thecollar 31, a brake band 34, and manual control means 35 therefor servesto hold the internal gear 30 against rotation and to cause rotation ofthe drum. At the opposite end of the drum from the brake band describedis a flange 36 having a braking surface 37 formed thereon which isengageable by a brake band 38 having manual operating means 39. When thebrake band 38 is applied and the brake band 34 released, the drum willbe held stationary and the member 31 rotated as will be shortly madeclear. Secured to the sleeve 9 outside of the hanger 10 is a windingmember 40 over which a rope may be wound in such a manner as to permitit to be hauled in, the member 40 corresponding in its operation to acapstan disposed in a horizontal position. For convenience, in certainof the appended claims, the term capstan is, therefore, used.

From the foregoing description the mode of operation of this mechanismwill be readily apparent. When the brake band 34 is applied, the member31 will be held against rotation and accordingly the internal gear 30will be stationary. Upon supply of fluid to the rotors 12 and 13, theywill revolve, causing rotation of the train of gears 21, 22,

the brake band 34 under which circumstances the member 31 will rotatewith the drum when the air is cut ofi, or at a greater speed if the airis still supplied to the motor. It it is desired to employ the windingmember 40, the brake band 38 may be applied and the brake band 34released, which will result in the rotation of the member 40; and bytakin one or two turns about this member, a arge Weight can be easilyhandled.

If it be desired to use this apparatus for the operation of a jib crane,it may be readily employed with such a device by locating a sn-ubbingpost adjacent the member 4C0 and passing the rope which is to shift theboom of the crane about the winding member 40. It will then be possibleto raise or swing the boom as desired by applying the brake member 38and releasing the brake band 33.

lWhen the boom has been moved to the :de-

sired position, the rope wound upon the member 40 may be either fastenedover the snubbing post :by half hitches or may be released and eitherbefore or after movement-of the boom, as the case may be, application ofthe brake band 34 and release of the brake band 38 will effect raisingof the load to be handled. The device may also be used to handlesubmarine drills, the main drum handling the drill itself while thesmaller member 10 can be used to handle drill steels or vice versa.

While I have in this application specifically described one form whichmy invention may assume in practice, it will be understood that thisform of the same is shown for purposes of illustration and that theinvention may be modified and embodied in various other forms withoutdeparting from its spirit or the scope of the appended claims.
